The specific steps for repairing Vizio televisions vary depending on the exact model and the nature of the issue. For example, fixing a black screen could require either checking the input ports for a malfunctioning cable or replacing the power board. Similarly, sound issue solutions may include purchasing new internal speakers.
One of the most common issues with a Vizio television is failure of the screen to display the picture, typically showing only a black screen instead. To troubleshoot this problem, first check to make sure that the power light on the television illuminates when pressing the power button on the remote or the set. If the light doesn't turn on, the problem may be due to an issue with the button or the remote, which would require a less expensive solution. If it does turn on, examine the screen for flickering or lines. Also check each input port to rule out the possibility of a faulty device or cable.
If the problem is a lack of sound, try plugging a pair of headphones into the unit, if available, or route the sound into an external set of speakers. If the sound projects, then the issue is with the internal speakers. If no sound emits, then there is a problem with the main unit. Fixing a main unit problem typically includes purchasing replacement speakers.
